GOIB

Get Over It Blud
when someones obsessing over something that's just not worth the hastle or they can't do anything about

If someone just needs to get on with the rest of the day and forget what just happened because it's so insignificant so need to be told it doesnt matter but in a friendly manner

'I got a shit cut'
'GOIB just skin up'

'i think i failed that IT test'
'are you taking it'
'no'
'then GOIB'
